To examine and set more information about existing cells, use the Cell Properties... command (in menu Cell): The left side of the dialog lists cells by library. On the right are the properties of these cells.

The checkbox "Disallow modification of anything in this cell", allows you to control whether the contents of a cell is editable or not. When modification is disallowed, no changes may be made. This is useful when you want to allow examination without accidental modification.

The checkbox "Disallow modification of instances in this cell", also prevents changes to the selected cell, but in this case, only instances of sub-cells are locked. This is useful when you have a correct instance placement and are doing wiring.

If you make a change that has been disallowed, a dialog appears that asks if you want to override the lock. You may make the change ("Yes"), disallow the change ("No"), or remove the lock ("Always", which unchecks the locks in this dialog). |

The check box "Part of a cell-library" indicates that this cell is from a library of standard cells and should be treated accordingly. Buttons on the right allow you to set or clear these flags for all cells in the library.

The "Expand new instances" and "Unexpand new instances" buttons choose whether newly created instances of this cell are expanded (contents visible) or unexpanded (drawn with a black outline) See Section 3-4 for more on expansion.

The "Characteristic Spacing" is the spacing of this cell when arrayed (see Section 6-4).

Each cell is tied to a specific technology. The cell's technology is set when the cell is created, according to the view type. Schematic views are given the schematics technology (see Section 7-5-1); Icon views are given the Artwork technology (see Section 7-6-1); Layout views are given the default layout technology. You can change the technology that is associated with a cell by using the "Technology" popup.

The lower-right has frame controls for the cell. The frame is a border that is usually drawn around schematics. You can set the frame size, whether it is wider (Landscape mode) or taller (Portrait mode), and whether a title box is drawn in the corner. Additionally, you can set the designer name to be drawn for each cell. Other information in the title box (company name, project name) are set on a per-user or per-library basis with the "Frame" preferences (in menu File / Preferences..., "Display" section, "Frame" tab). See Section 7-5-2 for more on frames.
